The cash doesn't just roll in when the customers aren't idiots.
The moaning developers are the ones who expect to make money simply because they produced an app. They underestimate the importance investment in self promotion. Their philosophy doesn't work on the PC, and the only reason it worked on the iPhone is because it became trendy.
Android users are smarter than that. They quickly learn that the market is crap, and that most apps aren't worth the $3 charge to their credit card. Google needs to improve the market, but the average screen-size is significantly smaller than an iphone, so usability will always be an issue. Thus, developers who expect big returns need to realize how to reach their target audience outside of the market.
Ultimately, the only effective way to locate apps now is through QR-code or SMS links delivered via aggregate websites. Compared to real websites, even the iPhone market sucks, so when more people start using their computers as a hub to enhance their phone, the shortcomings of a the built in market become negligible.
That jump is not something Google can do alone, the developers need to get the ball rolling through their own grass-roots effort. Honestly, most Android users are tech savy anyway, so it shouldn't be that hard.
